'''Sekinin barai''' {{kana|責任払い}}, or the rule of '''pao''' {{kana|パオ}}, forces a player whose discard is used to form an apparent [[yakuman]] to be liable for partial or full payment if the yakuman-holder wins. It is generally used for yakuman hands only, but certain rules also invoke pao for [[rinshan kaihou]]. Only certain types of yakuman are affected by pao; this will depend on the ruleset.

When the last group of a yakuman is called for an open [[kan]], the discarder is still liable for pao. This may not make sense as first, since the yakuman already existed without needing the kan.

To explain how liability works with "the responsibility of completing an ensured yakuman", it is better to switch to the opponent's point of view. When a yakuman-holder has called for two groups of dragons, daisangen is not guaranteed ''in the opponent's eyes''. Once an opponent discards the third dragon, and it is called for a kan, daisangen becomes guaranteed ''in the opponent's eyes''. So, when discarding a tile used for a kan, pao is still invoked: from the opponent's point of view, daisangen goes from not guaranteed -> guaranteed.
